最初にデータが正常に挿入されたときにデータベースが作成されたときに、テーブルにデータを挿入していますが、アプリを閉じて再起動するとエラーが発生します:
Error inserting id=1 new=1 title=sample page previous=0 color=0 next=2 state=1 header= "";
android.database.sqlite.SQLiteConstraintException: error code 19: constraint failed

これは私が使用しているコードですMainActivity.java
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
dataSource = new ContentsDataSource(this);
dataSource.open();
parseAndIsertData();
}
@Override
protected void onResume() {
// TODO Auto-generated method stub
super.onResume();
dataSource.open();
}
@Override
protected void onPause() {
// TODO Auto-generated method stub
super.onPause();
Log.i(MY_TAGT, "OnPuse() called");
dataSource.close();
}
private void parseAndIsertData() {
// Creating JSON Parser instance
MyJSONParser jParser = new MyJSONParser();
contentDataObject = new ContentDataObject();
// getting JSON string from URL
JSONObject json = jParser.getJSONFromUrl(BASE_URL);
try {
// Getting Array of Contents
jsonArray = json.getJSONArray(MOBILE_CONTENT);
// looping through All Contents
for(int i = 0; i < jsonArray.length(); i++){
contentDataObject.setId(jsonArray.getJSONObject(i).getInt(MOBILE_CONTENT_ID));
contentDataObject.setTitle(jsonArray.getJSONObject(i).getString(MOBILE_CONTENT_TITLE));
contentDataObject.setFulltext(jsonArray.getJSONObject(i).getString(MOBILE_CONTENT_FULLTEXT));
contentDataObject.setState(jsonArray.getJSONObject(i).getInt(MOBILE_CONTENT_STATE));
contentDataObject.setNewValue(jsonArray.getJSONObject(i).getInt(MOBILE_CONTENT_NEW));
contentDataObject.setHeader(jsonArray.getJSONObject(i).getString(MOBILE_CONTENT_HEADER));
contentDataObject.setColor(jsonArray.getJSONObject(i).getInt(MOBILE_CONTENT_COLOR));
contentDataObject.setNext(jsonArray.getJSONObject(i).getString(MOBILE_CONTENT_NEXT));
contentDataObject.setPrevious(jsonArray.getJSONObject(i).getString(MOBILE_CONTENT_PREVIOUS));
contentDataObject = dataSource.create(contentDataObject);
Log.i(MY_TAGT, "Data Inserted " + contentDataObject.getId() + " Times");
}
//textView.setText(builder);
} catch (JSONException e) {
e.printStackTrace();
}
}
EDIT
データを挿入するためのコードdb
は次のとおりです。
// Insert into Database
public ContentDataObject create( ContentDataObject dataObject) {
// Content class
ContentValues values = new ContentValues();
values.put(DBHelper.MOBILE_CONTENT_ID, dataObject.getId());
values.put(DBHelper.MOBILE_CONTENT_TITLE, dataObject.getTitle());
values.put(DBHelper.MOBILE_CONTENT_FULLTEXT, dataObject.getFulltext());
values.put(DBHelper.MOBILE_CONTENT_STATE, dataObject.getState());
values.put(DBHelper.MOBILE_CONTENT_NEW, dataObject.getNewValue());
values.put(DBHelper.MOBILE_CONTENT_HEADER, dataObject.getHeader());
values.put(DBHelper.MOBILE_CONTENT_COLOR, dataObject.getColor());
values.put(DBHelper.MOBILE_CONTENT_NEXT, dataObject.getNext());
values.put(DBHelper.MOBILE_CONTENT_PREVIOUS, dataObject.getPrevious());
long insetId = database.insert(DBHelper.MOBILE_CONTENT_TABLE_NAME, null, values, SQLiteDatabase.CONFLICT_IGNORE);// Here it gives me error for SQLiteDatabase.CONFLICT_IGNORE
dataObject.setId(insetId);
return dataObject;
}
EDIT
テーブル クエリの作成は次のとおりです。
private static final String MOBILE_CONTENT_DB_CREATE = "CREATE TABLE "
+ MOBILE_CONTENT_TABLE_NAME + "( " + MOBILE_CONTENT_ID + " INTEGER PRIMARY KEY AUTOINCREMENT, " +
MOBILE_CONTENT_TITLE + " TEXT, " +
MOBILE_CONTENT_FULLTEXT + " TEXT , " +
MOBILE_CONTENT_STATE + " INTEGER , " +
MOBILE_CONTENT_NEW + " INTEGER, " +
MOBILE_CONTENT_HEADER + " TEXT , " +
MOBILE_CONTENT_COLOR + " INTEGER , " +
MOBILE_CONTENT_NEXT + " TEXT , " +
MOBILE_CONTENT_PREVIOUS + " TEXT );";
このエラーが発生する理由を見つけることができません。ありがとう
